 Combined
COFDM & QAM Modulator
with VHF & UHF Upconverter, DVB-T/H/C Modulator.
PCI 2.2, 32 bit, 33/66MHz 3.3V.
Bus Master DMA, Scatter /Gather Interface Protocol.
Windows 2000, XP Drivers and Linux Drivers & API.
Accompanied by DVSStation2 Alitronika's Application Software.
Supports DVB According to Standard A1010 Rev1 and EN50083.
Modulation of Transport Stream files from Harddisk.
Modulation of Transport Stream from the ASI or SPI inputs.
All modulation processes are carried out by the hardware so that
there is no load on the PC processor,
So there is no need for an expensive high performance
PC.
Supports Burst or continuous modes, 188 and 204 packet sizes.
RF & IF Section are in metal enclosure
for noise immunity and high performance
